Abstract (en)
[origin: EP4144325A1] The present disclosure discloses a dental scanning method and device, computer device, and a non-transitory storage medium. The method includes: scanning a dental model according to a preset scanning path to generate a first mesh model; inputting the first mesh model into a preset dental identification model for identification to obtain dental data; searching tooth cavity data from the dental data according to a preset cavity seeking algorithm; and performing supplementary scanning on the dental model according to the tooth cavity data to generate a dentofacial mesh model. According to the dental scanning method provided by the embodiment of the disclosure, by performing intelligent supplementary scanning on the dental model, the problems of low efficiency and high operation difficulty of supplementary scanning of the tooth model are solved, and the quality of the dentofacial mesh model is improved.
